Waterproof mechanism

ABSTRACT

A waterproof mechanism includes a seat body, a waterproof rubber ring and a board body. The seat body has a first receiving space and a second receiving space in communication therewith. The second receiving space is longer and wider than the first receiving space. A platform is formed at a junction between the first and second receiving spaces. An inclined sidewall extends from the platform to surround and define the second receiving space. The waterproof rubber ring is disposed in the second receiving space in tight abutment with the platform and formed with a perforation in communication with the first receiving space. The waterproof rubber ring has an inner periphery and an outer periphery. The inner periphery is formed with a connection channel for connecting with the board body. The outer periphery is formed with a protrusion section protruding from the outer periphery to the inclined sidewall in abutment therewith.

FIELD OF THE INVENTION

The present invention relates to a waterproof mechanism, and more particularly to a waterproof mechanism having multiple waterproof seals to enhance waterproof performance and achieve excellent waterproof effect.

BACKGROUND OF THE INVENTION

Please refer to FIGS. 1A, 1B and 1C. A conventional waterproof mechanism 1 includes a waterproof rubber ring 10, a board body 13 and a seat body 15. The seat body 15 includes a first receiving space 151 and a second receiving space 152. A platform 154 is formed at the junction between the first and second receiving spaces 151, 152. An upright sidewall 155 extends from the platform 154 to surround and define the second receiving space 152. The waterproof rubber ring 10 is disposed in the second receiving space 152. The waterproof rubber ring 10 is formed with a perforation 101 in communication with the first receiving space 151. The waterproof rubber ring 10 has an inner periphery and an outer periphery. The inner periphery is formed with a connection channel 103 for connecting with the board body 13. The outer periphery is leaned against the sidewall 155. A bottom section of the waterproof rubber ring 10 abuts against the platform 154 as a waterproof seal 16 (as shown in FIG. 1C).

In the case that external water/vapor or liquid infiltrates through the gap between the sidewall 155 of the seat body 15 and the outer periphery of the waterproof rubber ring 10, the waterproof seal 16 of the waterproof mechanism 1 is able to stop the water/vapor or liquid from infiltrating into the first receiving space 151 of the waterproof mechanism 1. Accordingly, the waterproof mechanism 1 can provide a waterproof effect.

However, the conventional waterproof mechanism 1 can only provide a limited waterproof effect. This is because that due to the weight of the board body 13, a downward pressing force is applied to the waterproof rubber ring 10. In this case, no component force directed to the sidewall 155 is applied to the outer periphery of the waterproof rubber ring 10. Therefore, no additional waterproof seal is provided between the outer periphery of the waterproof rubber ring 10 and the sidewall 155 to enhance the waterproof effect. Under such circumstance, the conventional waterproof mechanism 1 has only one single waterproof seal 16, (that is, the bottom section of the waterproof rubber ring 10 that abuts against the platform 154), for preventing the water/vapor or liquid from infiltrating into the waterproof mechanism 1. Once the water/vapor or liquid infiltrates through the waterproof seal 16, the water/vapor or liquid can infiltrate into the first receiving space 151 without being stopped by any other protection means (such as other waterproof seal). As a result, an article received in the first receiving space 151, (such as an electronic product, a 3C product, an LED product, a product likely to become damp or the like) may be damped with the water/vapor or liquid.

According to the aforesaid, the conventional waterproof mechanism has the following shortcomings:

-   1. The waterproof effect of the conventional waterproof mechanism is     poor. -   2. The conventional waterproof mechanism only has one single     waterproof seal. -   3. The conventional waterproof mechanism has poor waterproof     performance.

SUMMARY OF THE INVENTION

A primary object of the present invention is to provide a waterproof mechanism having excellent waterproof effect.

A further object of the present invention is to provide the above waterproof mechanism having multiple waterproof seals for enhancing waterproof performance.

To achieve the above and other objects, the waterproof mechanism of the present invention includes: a board body; a seat body having a first receiving space and a second receiving space in communication with the first receiving space, the second receiving space being longer and wider than the first receiving space, whereby a platform is formed at a junction between the first and second receiving spaces, an inclined sidewall extending from the platform to surround and define the second receiving space; and a waterproof rubber ring disposed in the second receiving space in tight abutment with the platform. The waterproof rubber ring is formed with a perforation in communication with the first receiving space. The waterproof rubber ring has an inner periphery defining the perforation and an outer periphery leaned against the inclined sidewall. The inner periphery is formed with a connection channel for connecting with the board body. The outer periphery is formed with a protrusion section protruding from the outer periphery to the inclined sidewall in abutment therewith. The waterproof mechanism of the present invention has multiple waterproof seals to enhance waterproof performance and achieve excellent waterproof effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIGS. 2, 3 and 4A. According to a preferred embodiment, the waterproof mechanism 2 of the present invention includes a board body 20, a seat body 22 and a waterproof rubber ring 24. The seat body 22 has a first receiving space 221 for receiving an article (such as an electronic product, a 3C product, an LED product, a product likely to become damp, a communication product or the like). The seat body 22 further has a second receiving space 222 positioned above the first receiving space 221 in communication therewith. The second receiving space 222 is longer and wider than the first receiving space 221, whereby a platform 223 is formed at the junction between the first and second receiving spaces 221, 222. An inclined sidewall 224 extends from the platform 223 to surround and define the second receiving space 222. Please refer to FIG. 4A, which is a sectional assembled view of the preferred embodiment of the present invention. The platform 223 is formed as a step section of the seat body 22.

The waterproof rubber ring 24 is disposed in the second receiving space 222 in tight abutment with the platform 223. The waterproof rubber ring 24 is formed with a perforation 241 in communication with the first receiving space 221. The waterproof rubber ring 24 has an inner periphery 243 defining the perforation 241 and an outer periphery 244 leaned against the inclined sidewall 224. The inner periphery 243 is formed with a connection channel 2431 for connecting with the board body 20. The outer periphery 244 is formed with a protrusion section 245 protruding from the outer periphery 244 to the inclined sidewall 224 in abutment therewith. The protrusion section 245 has at least one first protrusion flange 2451 and at least one second protrusion flange 2452. The first and second protrusion flanges 2451, 2452 are formed on the outer periphery 244 in immediate adjacency to each other (not shown) or at intervals (as shown in FIG. 4A).

In addition, in accordance with the demands of appearance and waterproof effect of the waterproof mechanism 2, the outer periphery 244 of the waterproof rubber ring 24 can be designed with an inclination equal to or unequal to the inclination of the inclined sidewall 224. That is, the outer periphery 244 can be parallel to the inclined sidewall 224 and have an inclination equal to the inclination of the inclined sidewall 224 as shown in FIG. 4A. Alternatively, the outer periphery 244 can be unparallel to the inclined sidewall 224 and have an inclination unequal to the inclination of the inclined sidewall 224. In this embodiment, the outer periphery 244 has an inclination equal to the inclination of the inclined sidewall 224 for illustration purposes only.

Referring to FIG. 4A as well as FIG. 3, the first protrusion flange 2451 protrudes from the outer periphery 244 to the inclined sidewall 224. The first protrusion flange 2451 has the configuration of a semicircle, a semi-ellipse or any other suitable geometric pattern. The first protrusion flange 2451 tightly abuts against the inclined sidewall 224 as a first waterproof seal 26 for hindering (or stopping) external water/vapor or liquid from infiltrating into the waterproof mechanism 2. Due to the weight of the board body 20, a downward pressing force is applied to the waterproof rubber ring 24. In this case, a downward pressing force is simultaneously applied to the first protrusion flange 2451 of the waterproof rubber ring 24 to make the first protrusion flange 2451 tightly abut against the inclined sidewall 224 to form the first waterproof seal 26.

The second protrusion flange 2452 is positioned below the first protrusion flange 2451 and protrudes from the outer periphery 244 to the inclined sidewall 224. The second protrusion flange 2452 has the configuration of a semicircle, a semi-ellipse or any other suitable geometric pattern. The second protrusion flange 2452 tightly abuts against the inclined sidewall 224 as a second waterproof seal 27 for hindering (or stopping) external water/vapor or liquid from infiltrating into the waterproof mechanism 2. In similarity to the first waterproof seal 26, due to the weight of the board body 20, a downward pressing force is applied to the second protrusion flange 2452 of the waterproof rubber ring 24 to make the second protrusion flange 2452 tightly abut against the inclined sidewall 224 to form the second waterproof seal 27.

The first protrusion flange 2451 protrudes from the outer periphery 244 by a protrusion length. The second protrusion flange 2452 also protrudes from the outer periphery 244 by a protrusion length. The protrusion length of the first protrusion flange 2451 is larger than or equal to the protrusion length of the second protrusion flange 2452. In the case that the inclination of the outer periphery 244 is equal to the inclination of the inclined sidewall 224, the protrusion length of the first protrusion flange 2451 is equal to the protrusion length of the second protrusion flange 2452 (as shown in FIG. 4A). In the case that the inclination of the outer periphery 244 is unequal to the inclination of the inclined sidewall 224, the protrusion length of the first protrusion flange 2451 will be larger than the protrusion length of the second protrusion flange 2452 (as shown in FIG. 4B).

Furthermore, a bottom section of the waterproof rubber ring 24 tightly attaches to and abuts against the platform 223 as a third waterproof seal 28. In similarity to the first and second waterproof seals 26, 27, due to the weight of the board body 20, a downward pressing force is applied to the waterproof rubber ring 24 to make the bottom section thereof tightly abut against the platform 223 to form the third waterproof seal 28. The third waterproof seal 28 also serves to hinder external water/vapor or liquid from infiltrating into the waterproof mechanism 2.

When the waterproof mechanism 2 is placed in an environment where external water/vapor or liquid is likely to infiltrate into the waterproof mechanism 2, the first waterproof seal 26 of the waterproof rubber ring 24 serves to first stop (or hinder) external water/vapor or liquid from infiltrating into the waterproof mechanism 2. In case that the external water/vapor or liquid unexpectedly infiltrates through the first waterproof seal 26, the second and third waterproof seals 27, 28 will sequentially hinder the water/vapor or liquid from further infiltrating into the waterproof mechanism 2. Accordingly, the article received in the first receiving space 221 is protected from being damped with the water/vapor or liquid. The waterproof mechanism 2 of the present invention has multiple waterproof seals to enhance waterproof performance and achieve excellent waterproof effect.

According to the aforesaid, the waterproof mechanism of the present invention has the following advantages over the prior art:

-   1. The waterproof mechanism of the present invention is able to     provide excellent waterproof effect. -   2. The waterproof mechanism of the present invention has better     waterproof performance. -   3. The waterproof mechanism of the present invention has multiple     waterproof seals.
